Replacing ASM storage

edited May 14, 2018 3:14PM in Storage Management (ASM ACFS DNFS ODM) (MOSC) 3 commentsAnswered ✓

Hello,

We currently have a Grid/ASM 12c (12.1.0.2) single instance development environment (single ASM diskgroup/external redundancy) where the 1.5 terabyte database is stored on two 1 terabyte SAN disks using ASM.  The database SAN I/0 is slow and the plan is to switch to physical local hard drives to speed up database I/0 performance.

My question is - what would be the easiest way to migrate this ASM database to the new the new local storage?

Should I use the ASM replace disk command twice (e.g. replace each SAN with a physical local disk ) or should I add the new local disks first to the ASM diskgroup and then drop the SAN disks.

Howdy, Stranger!
